Built for my kids... might be useful for others?

Intended for laptop/desktop use, not for mobile. Uses Pyodide to execute all the code in the user's browser.

Content in the later sections is still a bit work-in-progress. Not sure what I'll do with it next, feedback appreciated!

(The first section is just multi-guess questions as part of the introductory content. Try any other section to get the full in-browser-code-execution experience.)
